Hi,

I've recently installed Garuda linux dragonized gaming edition (using garuda-dr460nized-gaming-linux-zen-210928.iso) on my desktop, and most things have gone surprisingly smoothly for a rolling release distro.

The only major problem I've had so far is that, whenever I log in to kde plasma, my entire home network loses access to the internet. This includes every PC and smartphone in the house, wired connections and wi-fi.

This is not much of a problem since I only log in about once every day, but it would be nice to have it fixed.

Although being speculation, I suspect this might have something to do with the latte dock, as one time it crashed and the same problem repeated as it started up.

So far I've tried changing the link negotiation in the KDE network connections settings to automatic, but that did not solve the problem.

So far I am loving garuda linux, and I wish to be able to daily drive it for the for the foreseeable future, so I hope you can help me fix this issue.

Hi there, welcome.
This is really strange!
Have you already tried changing the ethernet cable?
Maybe it's faulty and gives wrong signal to the router...

Hi, thanks for the quick response.

First, I would like to clarify something I forgot in the original post: the problem is temporary, after a minute or two the connection is restored.

I tried your suggestion, but the problem persisted. I even tried a direct connection to my modem instead of using a network splitter like I was using before, but the problem persisted.

I've tried changing the link negotiation to manual, but that did not fix the problem. I've also noticed that while the problem is active, the "online" indicator light in my modem turns off.

First thing to do if you suspect Latte could be causing issues on login is to introduce a 10 - 15 second Latte startup delay. Watch carefully for if your network connection starts properly while Latte is still dormant.

There are lots of things you can try to narrow the issue down.

The first thing is always cabling when dealing with Ethernet issues. The fact things work properly in Windows is irrelevant. Windows is far more fault tolerant than Linux of a marginal grade of cabling. Try another cable preferably cat7e or better.

Is your router's firmware up to date?

Do you have another router you can switch to temporarily? Any old one would be fine as a diagnostic step.

Do you have a spare Ethernet card you can swap in temporarily? Even a very old one will serve to narrow down if the card is the issue. A non r8168 based adapter would be best.

Try setting a static IP address on your Garuda computer.

Try disabling IPv6.

Try switching to the proprietary r8168 Realtek driver.

Probably a lot of other things to try as well, but I guess that's enough of a list for now.

Please provide feedback for all suggestions given.

Welcome to the forum.

Edit:

Also download and test different Garuda live versions such as Gnome, Xfce, and LXQt for comparisson.

I've just confirmed the problem is with latte. The problem only occurs when latte is started with autostart. Does not happen if I start it with krunner.

For now, I've disabled latte in the autostart and will manually launch it on startup.

I hope you can help me figure out this issue so I can use my desktop like normal.

Ok, I've found somethings out:

  • The problem occurs when latte is started from krunner or autostart.
  • The problem is independent from any widgets (Netspeed widget) or system tray icons (Networks icon).

I thing I will move this thread to the latte bug tracker, as it doesn't seem relevant to garuda linux.

Ok, I was really confident that the problem was with latte, but after uninstalling it and rebooting that proved untrue.

I think installing the proprietary network driver could help, but I do not know how to do that, so if you could guide me that would help.

Edit: Of course you just have to install a package to install the driver. I'm new to linux (lol)

Installing the driver did not fix the issue. I also tried booting with lts kernel instead of zen, but that did not fix it either.

The problem was not happening in the live version before, but now it is. Both the dragonized and dragonized-gaming live ISOs have the problem.

The xfce live ISO does not have the problem.

Probably your next best move would be to test the KDE barebones edition. If it also doesn't work correctly then you'll know this is a KDE issue. If the barebones edition does work correctly then it is likely an issue with the Dragonized version's configuration or package choices.

It's all a process of elimination that can be very time consuming and tedious.

Be sure to test a static IP configuration.

Good luck.

The KDE barebones edition does not have this problem.

A static IP seems to solve the issue.

Thank you for your help.

I marked the relevant suggestion post as "Solution".
If something changes (hopefully not), we can remove that flag, of course.
